I e-mailed Billy Godbolt last week to see if I could get a little more V-Rod specific turbo cam information. He pretty much told me the same thing he said in the article. If it is a good modern turbo, and it is matched up to the engine properly, the manifold pressure and the back pressure should be close to equal. If this is the case, overlap is not going to be an issue. He said once you start getting higher back pressure than intake pressure, the engine will become real overlap sensitive. He said he thinks the SE-2's would work good in a turbocharged race engine, but if you are worried run smaller cams. Keep in mind I'm still trying to learn more about what works best in a turbocharged engine cam wise and this is just one cam designer's opinion.
